To all whom t may concern.'

Be it known that I, LEOIMBLUM, a citizen residing at the city and county of Pueblo and State of Colorado, have invented certain-new and useful Improvements in Storage-Battery Casings; and I do deciare'lie following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being' had to the accompanymg drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates and has special reference to the cell construction.

It is the object of this invention to provide av multiple cell that is especially well adapted for automobile ignition and starting batteries, and which can be used for replacing cells for any make of storage bat- It isa further object of this invention to provide a multiple compartment cell that can easily be made, and in which the batv tery elements can be readily assembled in such a manner as to producea battery of simple and cheap construction and neat appearance and in which the connectors between the several battery elements of the.

cells will bc enclosed within the cells and thus be concealed from view and protected from inJury and possible short circuits.

In order to more clearl describe-my invention, I shall have re erence to the accompanying drawin ,in whichf gig. 1 is a top p an view of my battery ce i l f Fig. 2 is a longitudinal section taken on line 2 2, Fig. 1;

Fig. 3 is a transverse section taken on line 3 3, Fig.. 1;

Fig. 4 1s a top plan view of my cell fully assembled; l

Fig. 5 is a longitudinal section taken on line 55, Fig. 4; i

Fig. 6 is a transverse section taken on line @-6, Fig. 4;

Fig. 7 isv a plan view of my ventilatingv to storage batteries,

Fig. l() isa longitudinal 'section of the cover taken on line-10, Fig. 9.; i

The same reference numbers will be used to indicate the same parts throughout the several views. rectangular box of suitable material, such as hard rubber, which can'be moulded in a single piece; this box consists of a rectangw' several sets of battery elements into a series connection; The partition walls 4 and 5 are lower than the sides 2 and ends 3, so as to, provide space for a cover. The ends 3 of the bo'x ma be provided with handles 8, if itis foun 'desirable to do so.

In Fig. d I have shown a plan view of my battery fully assembled' with parts broken away so as to show some of the inside connections. The cover 9 is'made in one piece and is provided with holes 10 for the reception of vent plugs 11 andan o ening 12in each end for the reception o the terminal lugs 13, while holes` 14 are provided whereby connection ma the two poles of each cell for t e purpose of testing the voltage of each cell separately. The cells are each provided with the usual battery plates 15 which are alternately positive and negative; the plates of each' polarity are connected together. The positive elements of one end cell are connected to a terminal lug 13 which projects through one of the holes 12 in the cover 9, and the negative elements of the `other end" cell are connected to another terminal lug 13 which In Fig.. 1 I have shown a' be made to.

cell and the positive elements of thev is divided by` transverse last named end cell are joined by means f i connector bars 16 with -positive and ne tiv ey elements, respectivelyyof the centra cell. Bars 16 are, of course, covered with paint or other acid dproof current-resisting. material, and exten from one cell to the other through notches 7 in partitions, 4 and 5, and

.readily escape fromJny plug,

are located below the cover. In this manner the battery top is made muchneater in appearance, as only two terminal lugs are exposed thereon. By inserting a conductor through holes 14, contact` can be made with bars 16 for the purpose oftesting the voltage of each cell.

In order to seal the cover in place, I bevel the upper edges as indicated by 17 and pour sealing "compound in the triangular channell thus formed between the cover and the sides of the box, as indicated by numeral 18. In order to seal the space between bar 16 and slot 7, and the cover 9 and the tops ofthe partition walls 4 and 5, the tops of the latter are provided with channels 19, whichmay be semi-circular in shape, and the 4lower surface of the cover is provided with semicircular channels, which register with the channels 19 in the manner shown in Fig. 5. Sealing compound is then introduced into the channels between the cover and the partition walls. Suitable holes may be provided in the cover for the purpose of introducing the sealing compound.

In order to permit the escape of gas from the cells withoutlpermitting the elcetrol te to escape, I have shown a Ventilating p ug 11 which I secure in holeslO of the cover. This Ventilating plug is shown in Figs. 7 and 8, and consists of a tubular member having a circular flange 21 intermediate its ends. The portion of the plu below the flan e is preferably screw-threaded as indicate by 22. The upper end of the plug has a reentrant portion 23 provided with a central opening 24. It is evidentthat gas may but it is very difficult for liquids to escape therethrough, andif some electrolyte should escape, it will be received in the funnel-shaped top of the plug and will flow back into the cell. From the above it will be seen that I have provided a multiple cell battery box or-casing that can be moulded in a singlepiece, and which is so designed that the connection between the several cells may be made with- --in the .box and underneath the cover, whereby a. battery of much neater appearance is produced. My battery lis'provided with a single cover for the several one-piece box and single cover result 1n a much cheaper construction as well as a neater one. walls with notches 7, the plate straps or cell connectors can be used to connect the cells 'togthen thus eecting a considerable saving in material. The one-piece box and cover also permit an easy means of securing the terminal extensions 13 in place by means of lugs 25, thereby aidingin keeping the cable terminals from corroding.

My unitary battery casing may be used for replacement purposes for any make of .their upper corners whereby cells, andl the providing the partition messbar commercial storage battery, and when so used the unitar replaced by in handles '8 may cover may be omitted and ividual cell covers, likewise be omitted and the unitary battery casing placed in a container such I claim is- 1. A unitary battery casing comprising a box having a plurality of transverse partitions, each ot whichis provided with a notch near the side of the box, and a channel in the top of each partition for the reception of a sealing compound.

2. A unitary battery casing of acid resisting, non-absorptive material, comprising .a plurality of cells separated by transverse partitions, said partitions having a' notch in a connector may passl from one cell to the tops of s aid partitions bein lower than the sidesof the casing where y a space is provided for a cover, and parallel spaced supporting ribs on the bottom of each cell.

3. A battery casing comprising a box having a plurality of transverse partitions, each ofwhich is provided with a notch in its upper surface for the reception of a connector, the partition members being lower than the sides of the box, whereby a space is provided fora cover, a cover in said space, said cover having an opening near each end for the reception of a terminal lug, aplurality of openin in said cover, ada-pted to receive vent p ugs, and openings in Asaid cover communicating with said connectors.'

4. A battery casing comprising a box having a plurality o'f transverse partitions, each of which is provided w-ith a notch'in its upper surfacefor the reception of a connector, lsaid artitions 'being lower than the sides of the ox whereby space is provir ed for a cover, a'pair of s aced lugs on the top edge of said case, an a connector from said terminal to said lug.

5. `A unitary-battery casing comprising a `box having a plurality of transverse partitions by means of which it is divided into a number of cells, a unitary cover Jfor said casing, and means for permitting electrical connectors nto pass from one cell to the other underneath said cover.

6. A unitary battery casing comprising a box having a plurality of transverse artitions by means of which it is divide into a number of cells, a unitary cover for said casing, means for permitting electrical ccnnections to pass from one cell to the other underneath the cover and means,I for permitting ytest connections to be made with said connectors.
